Multiple exostosis is associated with the autosomal dominant disorder and hereditary multiple exostoses (HMEs), are rarely growing around the ribs and the formation of a large lump into the thoracic cavity. It's generally agreed that when there are no symptoms present, a HME patient could either avoid any treatment or postpone the operation until adolescence. We present a 5-year-old boy with 4 ...
INTRODUCTION Osteochondromas (exostosis) are the most common neoplasm of bone and arise from the metaphysis of bones. Tumors of the chest wall comprise approximately 2% of all tumors of the body and may be primary or metastatic, benign or malignant. Osteochondroma is a common bone tumor but a rare tumor in the rib. It is often asymptomatic and observed incidentally. The tumors typically begin t...
Subungual exostosis is a benign calcifying projection that occurs on the distal phalanx beneath or beside the nail. The problems in treatment are frequent postoperative recurrence and nail deformity or loss. Here, we describe the case of a male patient with a subungual exostosis beneath the proximal region of the nail plate of the right big toe. A precise preoperative evaluation of the anatomic...
BACKGROUND Hereditary multiple exostosis (HME) is characterised by multiple osteochondromas that are distributed throughout the skeleton, invariably involving the shoulder girdle. Tumours within the subacromial space can cause secondary irritation of the rotator cuff and result in subacromial impingement syndrome. CASE PRESENTATION We describe a 19 year old female patient with HME who present...
Expansion of the Rib Head: A Novel Computed Tomographic Feature of Supernumerary Intrathoracic Ribs.
Intrathoracic ribs are very rare congenital anomalies. Approximately 50 cases have been reported in the literature till date. They are usually present on the right side, between the third and eighth ribs without sex predominance. They may originate from a vertebral body or the proximal or distal part of a rib. In most cases, they are asymptomatic, but they may be associated with developmental a...
The solitary osteochondroma, a common pediatric bone tumor, is a cartilage-capped exostosis. Hereditary multiple exostosis is an autosomal dominant disorder manifested by the presence of multiple osteochondromas. Linkage analysis has implicated mutations in the EXT gene family, resulting in an error in the regulation of normal chondrocyte proliferation and maturation that leads to abnormal bone...
A 79-year-old man was admitted for aortic valve replacement 10 years after coronary surgery. The computed tomography (CT) scan showed a 5—6-cm-long bony structure originating from the distal sternum with its tip directed towards the right ventricle (Fig. 1). The structure was resected (Fig. 2) and histopathological examination revealed an exostosis. Fig. 1. 3D CT scan showing impingement of the...
